-- End of Section --

SECTION 01 11 00 Page 2

Amendment No. 0003Amendment No. 0003 the material in the offshore borrow area is believed to be as indicated by the results of Government-conducted sampling. Vibrational core sample grain size distribution curves are included in Section 00842. Vibrational core logs are included on the drawings. Vibrational core logs for Fenwick are included in Section 00841 The locations of the vibrational core holes in the borrow areas are shown on the drawings. The information depicted on the vibrational core logs represent the results of subsurface explorations made on the dates indicated and can only be considered as conditions existing at that time. Boulders, cobbles, clay balls, and munitions and explosives of concern (MEC) may also be encountered in the borrow areas. The borrow areas are located in the vicinity of known World War II era firing ranges. See Section 01 35 30 MUNITIONS AND EXPLOSIVES OF CONCERN (MEC) CONSTRUCTION SUPPORT for all requirements related to potentially encountering MEC in the borrow areas.

1.4.2 Location of Borrow Areas

The locations of the borrow areas and the limits to which removal of material is permitted are shown on the drawings.

1.4.2.1 Maximum Allowable Depth for Removal

The maximum allowable depths for removal of material from the borrow areas are as indicated on the drawings. Unless specifically directed by the Contracting Officer, no payment will be made for material removed from below this depth or from outside the borrow area limits.

1.4.3 Nature of Borrow Areas

The surveys of the borrow areas shown on the drawings are the most recent survey available. The borrow area conditions are dynamic in nature.

Therefore the contours shown on the drawings may not be an accurate representation of the depths and conditions existing at the commencement of dredging operations under this contract.

1.4.4 Before- and After-Dredging Surveys

Before- and after- dredging surveys shall be conducted as specified in Section 01 71 23 SURVEY REQUIREMENTS and Special Clause: QUANTITY SURVEYS.

1.4.5 Commercial Fishing Equipment

The Contractor shall be aware that there is a potential for commercial fishing equipment (ie. conch pots, black seabass pots, and commercial gill nets), marked by buoys, that could be deployed within the borrow areas at the time of dredging. The Contractor shall exercise caution to avoid this gear to the maximum extent practicable. If the gear cannot be avoided, the Contractor may proceed at risk to his own equipment. The Corps of Engineers or the sponsor (DNREC) or both will attempt to notify the commercial fishermen of the dredging operations and have them remove their fishing equipment prior to dredging.

SECTION 35 31 00 Page 4

3.2 PRE-PLACEMENT CONDITION SURVEYS

The beachfill area conditions are dynamic in nature. Conditions existing during the preparation of this contract may not be an accurate representation of the beachfill area conditions existing at the commencement of beachfill operations. Consequently, the Contractor shall obtain pre-placement condition survey cross sections, in accordance with Section 01 71 23 SURVEY REQUIREMENTS. Upon receipt of the pre-placement surveys as specified in Section 01 71 23 SURVEY REQUIREMENTS, the Government will re-issue revised beachfill sections. Commencement of beachfill will not be permitted until these surveys have been submitted and approved, and revised beachfill section re-issued by the Government.

3.3 MAINTENANCE OF DRAINANGE OUTFALLS

The Contractor shall maintain drainage of all outfalls at all times throughout the duration of the contract.

3.4 REMOVAL OF STRUCTURES

All existing structures, including but not limited to, the volleyball poles and bases, will be removed by others.

3.5 PLACEMENT OF BEACHFILL

3.5.1 General

Beachfill material shall be placed and shaped to the beachfill template lines, grades, slopes, and elevations shown on the contract drawings. There shall be no pronounced ridges or wash holes in the final grades and slopes unless otherwise indicated. Beachfill lines and grades shall extend linearly between before- and after-beachfill survey lines as specified in Section 01 71 23 SURVEY REQUIREMENTS, with no scallops in planform contours.

The required placement quantity of sand between survey lines will be determined by the average-end-area method using the difference in cross-sectional area between (1) the cross-section surveys obtained by the Contractor before the beachfill operations in accordance with Section 01 71 23 SURVEY REQUIREMENTS and (2) the template lines shown on the drawings.

For placement, a vertical tolerance of plus 0.2 feet and minus 0 will be permitted on the berm portion of the beach. Beachfill shall be placed to the minimum seaward edge of berm and to the foreshore slope indicated on the drawings, however the Contractor may adjust the construction template by advancing the seaward edge of berm (at the same elevation) and adjusting the foreshore slope to achieve the required placement quantity within the footprint of the beachfill template shown on the drawings. An example of an adjusted construction template is attached to this section.

In the event that the berm elevation, the minimum seaward edge of berm or the required placement quantities are not met, the Contractor shall recommence beachfill operations until the requirements are met. The Contractor will not be required to recommence beachfill operations in the event of erosion and/or storm damage in areas where beachfill has been completed and the survey data demonstrates compliance with the contract requirements.

SECTION 35 31 00 Page 5

Payment will be made for placement only to the lines and grades shown on the contract drawings (see Measurement and Payment paragraph below). In the event the Contractor adjusts the construction template as specified herein, payment will be made for measured quantity, not exceeding the required placement quantity. Payment will not be made for material placed above the required berm elevation, or placed seaward of the toe of slope. The toe of slope shall be defined as the point of intersection of the template as shown on the drawings with the before-placement survey cross section.

The Contractor shall conduct his work operations so that no areas landward of the work limits shown on the Contract Drawings are disturbed.

Land-based equipment shall be used for grading the beachfill material.

3.5.2 Removal of Debris

When MEC or MEC-like items are detected on the beach, the Contractor shall implement the procedures specified in Section 01 35 30 MUNITIONS AND EXPLOSIVES OF CONCERN (MEC) CONSTRUCTION SUPPORT. When any non-MEC item that physically should not be able to pass through the intake screening opening is detected in the discharge screening device, the Contractor shall implement the following procedures:

a. The Contractor shall stop dredging and beachfill work.

b. The Contractor shall report the incident to the COR.

c. Intake and/or discharge screening devices shall be repaired if necessary.

d. Beachfill and/or dredging work will not be permitted to re-commence until notification from the Contracting Officer.

During the operation of placing beachfill material, all debris resulting from construction operations shall be removed from the work site and disposed of at no additional cost to the Government. Such disposal shall comply with all applicable Federal, state and local laws. Such materials shall be removed from the site of the work before the date of completion of the work under these specifications. Debris may be temporarily stored on-site in a dumpster or roll-off box. Do not bury any debris collected in the screening device in the beachfill.

3.5.3 Placement of Beachfill Beneath Existing Beach Structures

Placement and grading of beachfill material by hand may be required beneath existing beach structures. The Contractor shall protect the existing beach structures from damage. Placement of beachfill material beneath structures shall be done in a manner that minimizes the ponding of water. If ponded areas are created due to the Contractor's operations the Contractor shall pump these areas dry at no additional cost to the Government. Any structures damaged shall be repaired at no additional cost to the Government.

3.5.4 Hydraulic and Hopper Dredges

All pipelines used with hydraulic dredges shall be kept in good condition at all times, and any leaks or breaks shall be promptly repaired. Material excavated by hopper dredge shall be loaded into bins or hoppers and pumped directly to the beachfill area by a means which shall prevent the loss of

SECTION 35 31 00 Page 6 any material into the ocean. Special care shall be taken to ensure that hoppers do not leak during any phase of the contract work.

3.5.5 Submerged Dredge Pipe

Barricades, warning signs, and lights shall be provided by the Contractor, subject to the approval of the Contracting Officer as part of the accident prevention plan, for the protection and safety of the public using the adjacent beach areas. The beachfill dredge pipe shall be clearly marked with buoy signs or other signage approved by the Contracting Officer at a distance of 200 feet seaward of the low water line at all locations that the dredge pipe is landed. This sign shall warn the public of the location and danger of the submerged pipe. All barricades, warning signs, and lights shall be installed prior to the start of any work. See Section 00800 SPECIAL CLAUSES for requirements to notify the Coast Guard to issue a "Notice to Mariners."

3.5.6 Removal of Stakes and Markers

The Contractor shall remove all stakes, markers, temporary fencing, burlap, or other items used in the construction of the beach immediately after completion and before approval of an acceptance section, or as otherwise directed by the Contracting Officer. All stakes, markers, temporary fencing, burlap, or other items used in the construction that become uncovered after approval of the acceptance section shall be removed within 24 hours of their detection.

3.6 SITE RESTORATION

If the Contractor removes any dune fencing and/or post and rail fencing or affects any dunes for access, the Contractor shall rebuild the damaged dune, replant any damaged dune grass, and reinstall fencing, as necessary, to restore the area to original conditions. Any materials required to establish or stabilize access points for vehicle use at those street ends shall be approved by the COR and provided and removed by the Contractor.

Any additional parking that the Contractor requires, outside the work limits, shall be coordinated directly with the appropriate local officials.
